Charles Hendry: Statistics on the generation capacity at the end of the calendar years 2006 to 2010 inclusive and the total amount of electricity generated during those years is available in table 7.4 of the Digest of UK Energy Statistics 2011 edition, copies of which are available in the House Library, and on the Department’s website at:
	http://www.decc.gov.uk/en/content/cms/statistics/publications/dukes/dukes.aspx
	Provisional estimates of capacity and generation data covering the first nine months of 2011 are published in table 6.1 of the December 2011 edition of Energy Trends, copies of which are available in the House Library, and on the Department’s website at:
	http://www.decc.gov.uk/en/content/cms/statistics/publications/trends/trends.aspx
	A provisional 2011 calendar year figure will be contained in the March 2012 edition of Energy Trends, which will be published on 29 March 2012, with final figures contained within the 2012 edition of the Digest of UK Energy Statistics, which will be published on 26 July 2012.
	Percentage changes in generation by main technology categories and yearly capacity changes during the period 2006 to 2010, derived from the data published in table 7.4 of the Digest of UK Energy Statistics are shown below. Year on year changes in generation are impacted by both changes in capacity and by external factors such as amount of rainfall and average wind speed.
